6mm & 7mm TCU- Youth Hunting Cartridge

[bluetopper]

I shoot and reload for both the 6 and 7mm TCU cartridges for my Contender handgun. I've always thought these two would make tremendous marketable youth hunting cartridges for a bolt action rifle. What they are is 223 brass with top half of the body blew out about .010" with a sharp shoulder and the neck expanded to 6 or 7mm. Thus creating more volume to hold about 3 more grains of powder than a 223. Both cartridges tremendously accurate and not picky about powders or bullets.

Always wanted a 6 tcu in a bolt action for a varmint gun.

When it comes to marketing a youth rifle, a guy has to overcome pretty simple logic: it’s not my rifle, it’s my kid’s rifle they’ll only use for a few years - do I want to make extra work for myself or spend extra money to get a non-standard cartridge which doesn’t shoot as flat as some available standard cartridges - say, .243win?

So that’s the hurdle. Why get something unique, rare, custom, etc when the .243win is on the market?

6-223, 25-45 sharps, and a few other necked mini-length cartridges like 6-6.8, 243 LBC/6mmAR are pretty popular among varminters. But we don’t generally see them favored for youth application.

I had a 6x47, and it was a fantastic light medium game cartridge/rifle combo. Now that the 6.5Grendel and X39s are readily available in short and mini guns, I dont see a great deal of value in building up something like a "kids" gun in 6x47. I would consider building one for ME on something like the savage 25, and then having a shorter stock for the kids to use....BUT they are probably going to just use what ever ive got on hand when the time comes.
I dont think its a bad idea, and would even try to dissuade you from doing it, but in a general sense i dont think its a great or necessary option.

I've shot a few deer with a 7br the tcu are nice as well.

I don't disagree, but I do very much agree with VT and LW assessments. My kids have .223, .22-250, .243, soon a mini action grendel, and whatever other fun things I decide to play with at their disposal.......why buy such a niche chambering?

My exact thoughts..

Sound great.

I solved the "youth rifle" problem with a lightweight build AR15 in 6.5Grendel.

If Ruger made a Stainless American in a 6.5 Grendel, I’d buy three (four, God willing we can finally have another child), for my wife, my son, and myself. New mcmillan stocks and new 1:7” twist Bartlein 20” barrels in 243 LBC (6mm Grendel variant) would be in order, but that would be a dandy little coyote and varmint rifle, and ridiculously fun to shoot.

Maybe we could ask them , I'd be in for a couple to tinker with!

I would be too...

 

[LoonWulf]

Actually we would probably be better off asking one of the major distributors......

 

[troy fairweather]

I'd like one as well.
